10 2 Fischer

Nickel (Ni) tends to promote methane formation as in a methanation process thus generally it is not desirable Iron (Fe) is relatively low cost and has a higher water-gas-shift activity and is therefore more suitable for a lower hydrogen/carbon monoxide ratio (H 2 /CO) syngas such as those derived from coal Get price
